JAMES YVELLSBY MURRAY, OF ST. GEORGE, CANADA, ASSIGNOR OF ONE- FOURTI'I TO SAMUEL JOHNSON, OF SAME PLACE.

WlNDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 643,676, dated February 20, 1900.

Application filed October 24, 1899. Serial No. 734,688. (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES WELLSBY MUR- RAY, a subject of Her Majesty the Queen of Great Britain, residing at St. George, county of Charlotte, Province of New Brunswick, Canada, have invented certain new and useful Improvements in Window-Sashes; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in window-sashes; and its object is to provide a window-sash which can be easily and quickly removed from the window-frame.

A further object is to provide a removable window-sash which is simple in construction, easily operated, and which can be manufactured at a moderate cost.

To these ends the invention consists in a removable window-sash constructed substantially as herein illustrated and described, and defined in the appended claim.

Referring to the drawings, in which similar letters of reference indicate similar parts, Figure 1 is a view in perspective of a windowframe provided with removable sashes constructed in accordance with this invention. Fig. 2 is a similar view showing one of the sashes removed. 7

In the drawings, A represents a sash-frame of any usual or preferred form, which may be constructed of wood or metal.

The window-sashes are constructed of a sheath B, in which the sash B is slidably mounted, and so constructed as to permit the ready removal therefrom of the sash B. The sheath B is constructed, preferably, of wood, though it may be formed of metal, and comprises the cross-bar b and the depending arms or sides b, which are provided with grooves b in their inner faces of awidth sufficient to receive the sides of the sash B. If preferred, the sides of the sash B and also the bottom thereof, as well as the lower ends of the arms I), may be suitably mortised or cut away to provide a close fit and give the sash and its sheath the appearance of an ordinary sash when in their normal position, as is clearly shown in the drawings.

It will be obvious from the above description that the sash B is adapted to slide freely in the grooves b of the sheath B and may be readily removed entirely therefrom when de= sired.

The sash B is provided at a suitable point with a pivoted latch 6 which is adapted to engage a suitable pin 12, secured on the sheath B, by means of which the sash may be se-' curely locked to the sheath when they are in their normal closed position. (Shown in Fig. l.)

The sheath B is provided with a pivoted catch 12*, which is adapted to engage an orifice in the window-frame to retain the sheath and sash in their proper position in the frame. It will be understood, however, that instead of this device for retaining the sash in its position in the frame the usual cord and weight may be used, if preferred.

When it is desired to remove a sash for any purpose, as for washing, repairing, &c., it is only necessary to raise the sheath to the top of the frame and disengage the latch b whereupon the sash may be readily withdrawn from the sheath and after having been washed or repaired returned to its former position.

It will be obvious that instead of constructing the sheath so that the sash can be removed from the bottom thereof it may be constructed so as to permit the sash to be removed from the top.

An important advantage in addition to those above mentioned incident to this invention is that the ordinary glass sash may be quickly and easily replaced by a sash having a wire screen.

The operation of this invention and its many advantages are believed to be sufficiently obvious in View of the above description and necessitates no further detailed ex planation.

\Vhile Ihaveherein shown a preferred form of carrying my invention into effect, yet I' do not desire to limit myself to such preferred details of construction, but claim the right to inserted in said open side; and a latch pivoted to said sash and adapted to engage the pin of said sheath, whereby the sash may be locked to said sheath, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

JAMES VVELLSBY MURRAY.
